PATRICK CHARLES STEAVEN HENDERSON, OF PORTLAND, MAINE.

SPECIFICATION forming part of Letters Patent No. 328,944, dated October2'7, 1885.

Application filed July 22, 1885. Serial No. 172.334. (No model.)

To all whom it may concern.-

Be it known that I, PATRICK O. S. HEN DERSON, a citizen of the UnitedStates, residing at Portland, in the county of Cumberland and State ofMaine, have invented certain new and useful Improvements in InvalidsGonvertible Chairs and Beds; and I do hereby declare that the followingis a full, clear, and exact description of the invention, which willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to improvements in invalids beds such as used inhospitals; and it consists in adapting such a bed to be used as a chair.

In the accompanying drawings, illustrating my invention, in whichsimilar letters of reference indicate like parts in the differentfigures, Figure 1 is a side elevation showing how the bed is used whenthe occupant or patient is in the sitting posture. Fig. 2 is a top planview, and Fig. 3 is an end elevation showing the mechanism for operatingand sustaining the movable parts. Fig. 4 is a side elevation of the bed,showing the position of the parts when the patientis in horizontalposition. Fig. 5 is aperspective view of the mattress detached from thebed.

The letterA designates themain bed-frame, which is constructedsubstantially as in the common bed. To the side rails, B, are pivotedthe side bars, 0, of what I shall term the chair-frame. To givestrength,this chairframe may be provided with transverse rounds or rods,such as used in ordinary chairs. A strong piece of cloth, canvas, or avery thin mattress, D, is secured within thebed-frame to the foot-boardand side rails thereof up to the pivotal points of the chair-frame, fromwhich points the said cloth or canvas is secured to the chair-frame toits ends. This piece D is pro-' vided with slits a, through which thelegs of the patient project when in the sitting posture. This piece Dmay also be provided with an opening, I), for obvious purposes.

Eis a thick mattress supported on a light frame, E, and suspendedbeneath the piece D by means of cords e, which pass around pulleys f onthe bed-frame to a small windlass or bar, journaled in the bed-frame.This windlass or bar has a squared end, 71, upon which fits a crank orlever, whereby the mattress is raised or lowered. For retaining themattress in any position to which it is adjusted, I employ apawl-and-ratchet mechanism, 0.

The lower ends of the legs or bars O of this windlass being the same asthose for the mattress, no further description of them seems necessary.

Referring now to Fig. 5, the mattress'E may be constructed with a holeor concavity, b, to align with the opening I) in the canvas bottom D.This hole is to receivea vessel for use of the patient, and when thehole is not so in use it may be filled with a correspondinglyshapcdpiece or plug, d.

The operation and use of my bed are as follows: \Vhen the patientdesires to lie in the horizontal position, the thick mattress E iselevated to bear against the piece D, as seen in Fig. 4,when it willform the desirable soft or yielding surface upon which to rest, as inordinary mattresses. WVhen the patient or occupant wishes to assume thesitting posture, the mattress E is lowered and the chair-frame is turnedon its pivots to the desired inclina tion, and the patient allows hislegs to project through the slits a, and his feet rest upon the loweredmattress, as clearly shown in Fig. 1. The adjusting of these parts isnecessarily performed by the attendant or physician.

It will be seen that my invention will be particularly useful inhospitals, where many patients are often so crippled or ill that theycan not be conveniently taken from their beds.

Any obvious modification or location of the means for operating themovable parts of my invention may be employed without departing from thespirit of my invention.

If desirable, the piece between the slits in the piece or thin mattressD may be detachable at its connection with the foot-board.

Having now described my invention,what I claim, and desire to secure byLetters Patent, 155-- 1. A bed-frame, the chair-frame pivoted withinsaid bedframe, a cloth or thin mattress secured in said bed-frame and tothe pivoted chairframe,and slits or openings in said piece D for thelegs of the occupant, combined with mechanism for adjusting andretaining said chair-frame in position, substantially as described.

2. A bed-frame, the chair-frame pivoted chair-frame, and slits oropenings in said piece within said bed-frame, a cloth or thin mattress,

In testimony whereof I affix my sign ature in D,secured in said bedframe and to the pivoted presence of two Witnesses.

D for the legs of the occupant, combined with a thick mattress, E,suspended beneath said piece D, and means for adjusting and supportingsaid chair frame, substantially as de- PATRICK CHARLES STEAVENHENDERSON".
